Pocket-lint has a rumour up that Facebook is interested in acquiring Opera to kickstart their own move into the browser market, to compete with Mozilla, Google, and Microsoft. While it would mean much-deserved recognition for Opera, I actually hope such a deal does not go through - for entirely selfish reasons.

I would imagine it would be much cheaper for Facebook to build their own browser out of WebKit or some other open project, especially given Zukerberg's history as a software guy. It might take a little bit longer, but would involve less spending, less lawyers and much more positive publicity in the tech circles.

On the other hand, Facebook lately seems to have the "throw a wad of cash at it" approach to innovating.
